FIELD OF THE INVENTION

The present disclosure relates to novel and advantageous flamelesscandles. Particularly, the present disclosure relates to novel andadvantageous flameless candles simulating a realistic flame-likeflicker, are capable of emitting a scent, and/or allow users to moreeasily control the candles' operations.

BACKGROUND OF THE INVENTION

The background description provided herein is for the purpose ofgenerally presenting the context of the disclosure. Work of thepresently named inventors, to the extent it is described in thisbackground section, as well as aspects of the description that may nototherwise qualify as prior art at the time of filing, are neitherexpressly nor impliedly admitted as prior art against the presentdisclosure.

Traditional true flame candles, when lit, provide a pleasant ambience inmany homes and businesses. Traditional candles may also be scented,adding a pleasant aroma. While the wax typically has a scent, even whenthe candle is not lit, this scent may be amplified when the candle islit. Traditional candles however, provide a variety of hazards includingrisk of fire, damage to surfaces caused by hot wax, and the possibleemission of soot. Flameless candles have become increasingly popularalternatives to traditional candles. With no open flame or hot meltedwax, flameless candles provide a longer-lasting, safe, and cleanalternative. There are flameless candles available that use incandescentlamps or light-emitting diodes (LEDs) as a light source. However, suchflameless candles are easily distinguishable from their traditionalcandle counterparts. One problem is that flameless candles generallycannot suitably simulate the natural flicker of an actual flame asviewed by the naked eye. Another problem is flameless candles have notbeen able to provide a scented feature that simulates the desiredscented feature of a traditional candle, particularly when lit. Inaddition, flameless candles typically have one or more switches on thebase of the candle to turn the candle on, off, or into a flicker mode.This requires the user to awkwardly or inelegantly take the candle offits resting place.

Thus, there is a need in the art for a flameless candle that isaesthetically similar to a traditional candle. More particularly, thereis a need for a flameless candle that emits a more natural, flame-likeflicker of light, is capable of emitting a scent, and allows the user torelatively easily control the candle's operations.

Turning now to FIGS. 4A-4G, other embodiments of an electronic flamelesscandle are shown. Generally, as illustrated in the flameless pillarcandles of FIGS. 4A and 4F, the body 420 of a flameless candle 400 maybe comprised of a top surface 422, a bottom surface 424 upon which thecandle rests, and a sidewall 426 between the top surface 422 and thebottom surface 424. The body 420 may have desirable translucent,luminescent, and aesthetic properties to mimic the look and feel of atraditional candle. The body 420 may be made from one or more materials,including but not limited to, wax, paraffin, glass, polymeric materials,or any combination thereof.

Referring to FIGS. 4B and 4G, the flameless candle 400 may include anouter shell 410A, 410B and an inner core 400B. The outer shell 410A,410B may be removed from the inner core 400B, in some embodiments. Theinner core 400B may, in some embodiments, be used as a flameless candlewithout the outer shell 410A, 410B. In one embodiment, the inner core400B may resemble a gel or oil candle. The inner core 400B may or maynot resemble the appearance of a traditional candle type. It should beappreciated, in one embodiment, that a user may be able to selectbetween multiple candle types (e.g., the outer shell and inner core incombination or just the inner core). The outer shell 410A, 410B may bereplaced onto the inner core 400B. In various embodiments, the outershell 410A, 410B may be mechanically connected to the inner core 400B,such that the sleeve may resist accidental removal. For example, theouter shell 410A, 410B may mechanically connect to the inner core 400Busing a bayonet connection, a snap fit, a magnetic fit, a friction fit,or any other suitable method of connection. The outer shell 410A, 410Bmay additionally or alternatively be substantially permanently connectedto the inner core 400B.

In addition, the outer shell 410A, 410B may additionally be exchanged,after removal, thereby allowing a user to vary between one or moreaesthetic candle outer shell options. In one example only, a white outershell 410A, 410B may be removed and a green sleeve may alternatively bemechanically connected to the inner core 400B, thus changing the pillarcandle from white to green. It should be appreciated that any number ofvarying sleeves may be used to vary the color, transparency, texture,shape, height, scent (discussed more below), any other feature, or anycombination thereof.

The top surface 422 may generally refer to the top portion of thecandle. The top surface 422 may include one or more structuralcomponents, in various embodiments. In one embodiment, the top surface422 may include an indented central portion 428, a lip 421, an interiorwall 427 between the lip 421 and the indented central portion 428. Theindented central portion 428 may resemble a top surface of a used orpartially melted traditional candle, where the wax may have been reducedby melting from the heat of the open flame in order to continue feedingthe flame. In other embodiments, the central portion may not beindented. The sidewall 426 and interior wall 427 may cooperate to createa lip 421 on the top surface 422. As seen in the embodiment of FIG. 4A,the sidewall 426 and lip 421 may cooperate to have a varied heightthereby resembling the visual appearance of a used traditional candlewhere the wax has melted due to the flame of the candle. In otherembodiments, the sidewall 426 and lip 421 may have a constant height toresemble a new candle that has not melted, as seen in FIG. 4F. Invarious embodiments, the lip 421 may additionally or alternatively bemoldable, such that a user may change the shape. That is, a user may beable to mold the lip 421 to reflect the look of a traditionally usedcandle and/or mold the lip 421 to reflect the look of a traditionallynew(er) candle. The top surface 422 and bottom surface 424 may becircular and the sidewall 426 may extend circumferentially around thelongitudinal axis, resulting in a cylindrical body 420. However, othershapes or configurations are possible and within the scope of theinvention including, but not limited to, a cube, a cuboid, a cone, apyramid, or a sphere. The bottom surface 424 may generally be flat,resulting in a stable condition of the candle when placed on a table,shelf, or other suitable flat surface.

The top surface 422, bottom surface 424, and sidewall 426 may cooperateto form a cavity 448. In some embodiments, as illustrated in FIGS. 4Aand 4F, a cavity wall 446 may define the cavity 448. In someembodiments, the cavity wall 446 may be comprised of a material that issubstantially clear. In other embodiments, the cavity wall 446 may bepartially transparent. It should be appreciated that any degree oftransparency may be used. A cavity wall 446 that is less than opaque mayallow light, from an active light source, to transmit outside the cavity448, thereby making the body 420 of the flameless candle 400substantially more translucent. In some embodiments, the cavity wall 446may have one or more regions of varying transparency. For example, anupper cavity wall 446A may be relatively more translucent allowing morelight to transmit out to the body 420. A lower cavity wall 446B may berelatively less transparent or opaque. The body 420 that correlates tothe lower cavity wall may thus be less translucent. By using a cavitywall region 446A with a relatively greater transparency, flamelesscandles of the present disclosure may better mimic a traditional candlewhere regions of the candle at or just below the current wick height aremore translucent due to the fact the light has to transmit through lesswax. Additionally, by using a cavity wall region 446B with a relativelylower transparency, the flameless candle 400 may better mimic areas oftraditional candles substantially below the current wick height wherethe wax is generally less translucent due to the light being unable totransmit, or transmit with the same brightness, through increasinglythicker areas.

The cavity 448 may house one or more of the internal components. Invarious embodiments, the internal components may be organized to providea substantially open area 444. The substantially open area 444 may allowmore uninterrupted space for a light source 456 to shine light onto thewax body 420 of the candle. That is, the substantially open area 444 mayallow light from a light source 456 to shine from within the cavity ontothe body 420 in a generally uninterrupted and, in some cases uniform,manner, which may produce additional luminescence on the body 420. Thebottom surface 424 may include a cover 434, that may allow easy accessto the power source compartment 436.

The Control Switch

As illustrated in FIGS. 4A and 4F, disposed in the center of the base ofthe central portion 428 of top surface 422 may be a control switch 430.In various embodiments, the control switch 430 may be a push button,toggle, slide, rotary selector switch, or any other suitable control. Invarious embodiments, the control switch 430 may be the singular methodto control any and all functions or modes of the candle, discussed inmore detail below. By activating the control switch 430, one or morefunctions or modes may be activated, such as the light source 456 maybegin to flicker. In alternative or additional embodiments, the bottomsurface 424 may include a lower control switch. It is understood thatone or more control switches and one or more other methods of activationmay be used, separately or in combination, to control the variousfunctions of the flameless candle 400.

In various embodiments, the control switch 430 may include a wickcomponent 431, a light source 456, and a sheath 432. The control switch430 may generally be configured to resemble a natural candle's wick 431.The wick 431 may be a generally flat or cylindrical structure thatprotrudes from the indented central portion 428. The wick 431 mayresemble a cored wick, a flat braided wick, a square braid wick, or anyother wick type. That is, the wick 431 may or may not be braided inappearance. The wick 431 may also have a ball or nub at the tip toresemble the mushrooming or carbonized ball that sometimes develops onnatural wicks. In addition, the wick 431 may be relatively thin. Invarious embodiments, the wick 431 may have a diameter of less than threemillimeters. In another embodiment, the wick 431 may be less than onemillimeter in diameter. In still other embodiments, the wick 431 mayhave a diameter of any suitable thickness. The wick 431 may also berelatively short. In various embodiments, the wick 431 may be less thanan inch long. In some embodiments, the wick 431 may be less than half aninch long. In a typical embodiment of the present disclosure the wick431 may be around a quarter inch in length, or shorter. In someembodiments, the wick 431 may be at least partially curved or bent. Inother embodiments, the wick 431 may be substantially straight. In someembodiments, the wick 431 may be black to resemble the look of a candlethat has been lit at least one time. In other embodiments, the wick 431may be white. In still another embodiment, the wick 431 may match thecolor of the body 420. It may be appreciated that the wick 431 may beany color.

In various embodiments, the wick 431 and one or more light sources 456may be merged to form the control switch 430. That is, the wick 431 andthe light source 456 may comprise a single component (the control switch430) that, for example, may be pushed down to activate or deactivate oneor more functions of the flameless candle 400. The wick 431 and lightsource 456 may be manufactured as a single unit and/or mechanicallyconnected. For example, the light source 456 may be placed into a moldor die, which may be configured to resemble a wick. One or morematerials may be injected into the mold such that a control switch 430resembling a wick 431 is formed on or around the light source 456. Inanother embodiment, the wick 431 may be glued or fastened to the lightsource 456 after being molded. In various embodiments, the wick 431 ofthe control switch 430 may be comprised of plastic or a polymericmaterial. In other embodiments, the wick 431 may be comprised of glass,rubber, a metal alloy, or any other suitable material or combination ofmaterials.

In some embodiments, as seen in FIGS. 4D and 4E, the control switch 430may include a sheath 432, which may be formed around the wick 431 andlight source 456. In at least one embodiment, the sheath 432 may beformed around the wick 431 and light source 456 before the wick 431completely dries from the injection molding process. In variousembodiments, the sheath 432 may be clear. In other embodiments, thesheath 432 may be semitransparent. In still other embodiments, thesheath 432 may have one or more areas that are substantially opaque.However, it should be appreciated that the sheath 432 may be transparentenough to allow the light from the light source 456 to be transmitted.The sheath 432 may be a plastic, in some embodiments. It should beappreciated that one or more materials may be used individually or incombination to construct the sheath 432.

The cavity 448 may contain the electrical assembly 450, schematicallyillustrated in FIG. 4A. The electrical assembly may comprise one or morecomponents, including, but not limited to, a control switch assembly458, a power source 452, at least one circuit board 454, and a lightsource 456.

Control Switch Assembly

As seen in FIG. 4C, the control switch assembly 458 may be comprised ofone or more components. The control switch assembly 458 components mayinclude, but are not limited to, a control switch 430 (or control switch430), an internal push button 470, a retaining assembly shell 460, andone or more printed circuit boards (PCBs) 462, 464.

The control switch assembly 458 may comprise a retaining assembly 460.The retaining assembly 460 may have a circumferential portion 468 thatmates with a circular opening on an exterior surface 428 (also referredto herein as the indented central portion) of the candle body. Invarious embodiments, when installed within the body 420, the retainingassembly 460 may be configured to be flush with the surrounding exteriorsurface 428. In some embodiments, the retaining assembly 460 may have acentral lumen 469 through which the control switch 430 may be able toslide. The control switch 430 may be centrally disposed within thecentral lumen 469. The control switch 430 may be configured such thatthe light source 456 is flush with the exterior surface 428. Forexample, the light source 456 may be positioned both partially above andpartially below the exterior surface 428. By positioning the lightsource 456 partially above an exterior surface 428 of the flamelesscandle 400, the light source 456 may better emulate the bright light ofa flame from a traditional candle. By positioning the light source 456partially below the exterior surface 428, or within the cavity 448, thelight may shine from the cavity 448 out onto the sidewall 426 of thebody 420 thereby giving a translucent appearance to the body 420. It maybe appreciated that the light source 456 may be positioned at any pointabove or below an exterior surface 428 of the flameless candle 400.Furthermore, it may be appreciated that one or more light sources 456may be used, such that one or more light sources 456 are located above,or partially above, the exterior surface 428 and one or more lightsources 456 are located below, or partially below, the exterior surface428.

Embodiments of the present disclosure may include one or more printedcircuit boards, or PCBs. In one embodiment, the PCBs may include, butare not limited to, a main PCB 454, a light switch PCB 462, and a pushbutton PCB 464. In various embodiments, the light switch PCB 462 and thepush button PCB 464 may be located in the control switch assembly 458and contain electronics for connecting the various components of thecontrol switch assembly together and/or with the main circuit PCB 454.In other embodiments, all or any PCBs may be located exterior to thecontrol switch assembly 458. Any suitable location for any PCBs may beused.

Referring to the embodiment seen in FIGS. 4D and 4E, the control switch430 may be mechanically and electrically connected to a light switch PCB462. The light switch PCB 462 may be in direct or indirect electricalcommunication with the main PCB 454. The control switch 430 may beconfigured such that it causes the light switch PCB 462 to press,activate, and/or deactivate an internal push button 470. However, inother embodiments, the control switch 430 may directly press upon,activate, and/or deactivate the internal push button 470. The internalpush button 470 may be mechanically and electrically connected to a pushbutton PCB 464. The push button PCB 464 may be in direct or indirectelectrical communication with the main PCB 454. For example, when a userpushes down onto the control switch 430, the light switch PCB maydepress a button 472 on the internal push button 470. The depression ofthe button 472 may be configured to produce a communication between theinternal push button 470 and the push button PCB 464, such as, but notlimited to, completing the circuit connecting the push button PCB 464with the main PCB 454. The main PCB 454 may be configured to cause asignal to run to the light switch PCB 462, thereby activating one ormore functions of the light source 456.

The light switch PCB 462 and push button PCB 464 may be optimallyarranged, shaped and sized to facilitate light from the light source 456in the cavity 448 to shine into the open area 444. That is the PCBs 462and 464 may be relatively small, and positioned in such a way as tofacilitate light from the light source 456 positioned on one side ofPCBs 462, 464 to shine through or to the other side of the PCBs 462,464. In one embodiment, the light switch PCB 462 may be configured to beparallel to the light source 456, thereby allowing light to shine fromthe light source in a substantially 360 degree range, in reference tothe light switch PCB 462. The push button PCB 464 may be shaped andsized small enough to allow light to pass on one or more sides into theopen area 444 but remain large enough to support the internal pushbutton 470 and any mounting components. In other embodiments, the pushbutton PCB may be shaped and sized to fit substantially within or underthe internal push button 470. Any suitable size, shape, and arrangementof the PCBs 462, 464 may be used. In some embodiments, the PCBs 462, 464may be clear or semitransparent, thereby increasing the ability of lightfrom the light source 456 to shine from one side of a PCB 462, 464 tothe other side and into the open area 444.

Referring back to FIG. 4C, the retaining assembly 460 may comprise oneor more components that are assembled to hold the control switchassembly 458 within the candle body 420. The components may, in someembodiments, comprise a mating ring that rests upon the cavity wall 446.The body 420 may secure the retaining assembly 460 into place, on top ofthe cavity wall 446. In other embodiments, the retaining assembly may bemechanically connected to the cavity wall 446 and/or body 420, forexample, using a bayonet connection, a snap fit, a magnetic fit, afriction fit, or any other suitable method of connection. In someembodiments, the configuration of the retaining assembly 460 and theselected material may have desirable translucent, luminescent andaesthetic properties to mimic the look and feel of a traditional candle.In various embodiments, the retaining assembly 460 may be clear. Inother embodiments, the retaining assembly 460 may be semitransparent. Itmay be appreciated that any degree of transparency may be used. It mayalso be appreciated that the circumferential portion 468 that mates witha circular opening within the top surface 422 may appear opaque and waxlike while the rest of the retaining assembly has a higher translucence.A retaining assembly 460 that is less than opaque may allow light froman active light source 456 to better transmit down into the cavity 448,which may in-turn make the body 420 of the flameless candle 400 appearsubstantially more translucent. In some embodiments, the retainingassembly may be made from a wax, paraffin, glass, polymeric materials,or combinations thereof.

Power Source

Referring again to FIG. 4A, a power source 452 may provide power to theelectrical assembly 450, resulting in the light source 456 beingilluminated. The power source 452 may be disposed within a power sourcecompartment 436. The power source 452 may comprise one or more batteries480. The batteries 480 may comprise one or more batteries having one ormore sizes or shapes. The power source 452 may be adjacent to the cover434 and centrally located, allowing an ease of access to change thebattery. In other embodiments, the power compartment may be locatedproximal to the sidewall 426, superior to the rest of the electricalassembly, or exterior to the flameless candle 400. The power compartmentmay be located in any suitable location. The power source 452 may be oneor more standard alkaline batteries, one or more rechargeable batteries,a USB charged power source, a power cord, a power source charged byinduction charging, any other suitable source, or any combinationthereof.

The light source may illuminate the flameless candle. In variousembodiments, the light source may be a LED that comprises one or morediodes. In other embodiments, the light source may be an incandescentlamp. In still another embodiment, the light source may be a gasdischarge lamp. It may be appreciated that any suitable light source maybe used. In various embodiments, different colored lights may be used tobetter mimic the color of a flame. For example, in one embodiment, thelight source may by a combination of red, yellow, orange, and/or whiteLEDs. The lights may cooperate to mimic the colors of a natural flame.The light source may preferably be located on a midline of the body 420of the candle in order to mimic traditional candles, as seen in FIG. 4A.In other embodiments, the light source may be located more proximal tothe sidewall. In at least one embodiment, the light source may belocated superior to the transverse plane, or in the top half of thecandle. However, a light source located at any point within the body ofthe candle is within the scope of the present disclosure.

In various embodiments, the main circuit 54 or main PCB 454 may belocated anterior to the open area 444 and/or proximal to the powersource. In other embodiments, the main circuit 54 or main PCB 454 may belocated in any location. The main circuit 54 or main PCB 454 may be theonly circuit in some embodiments. In other embodiments, the main circuit54 or main PCB 454 may be comprised of a plurality of different circuitcomponents. In some embodiments, the circuit board components mayinclude but not limited to, a clock 76, an analog-to-digital converter80, a random address generator 84, a random sequence generator 90, andan output 92 may be located on the main circuit 54 or main PCB 454. Inother embodiments, one or more components may additionally oralternatively be located on the light switch PCB 462, on the push buttonPCB 464, or on any other circuit. The functionality of the circuitboards 54, 454, 462, and 464 are discussed below.

Function

The following discussion is directed to various functions of theflameless candles 10, 100, 400. While one or more of the variousfeatures may be implemented in any number of the disclosed embodimentsor any other embodiment contemplated by this disclosure they aredescribed in the context of the following example implementation.

The upper control switch 30, 430 and/or lower control switch 32, hereincollectively referred to as the control switch, may be in communicationwith a light source (or light) 56, 456, collectively referred to hereinas the light source or light. The control switch may be a push button,toggle switch, slide switch, or any other suitable component. Thecontrol switch may be configured to, when selected by the user, modifythe frequency of a light's flicker, the luminescence of the light, thecolor of the light, or the timer settings of the light. In at least oneembodiment, the control switch may be a push button, which whendepressed selects a particular mode of the candle. In one embodiment,the modes include, but are not limited to, a flicker mode, a staticlight mode, and an on/off mode. For example, depressing the push buttonof the control switch may activate the light source in flicker mode. Alight in flicker mode may randomly dim and brighten in such a way thatmimics a flame from a traditional candle. Depressing the push button asecond time may activate the light source in static mode. A light instatic mode may be on but may not flicker. Depressing the push button athird time may activate a timer mode. A light in timer mode mayautomatically turn off after a set time period. Depressing the pushbutton a fourth time may deactivate the light, or result in an off mode.Any suitable means of activation or deactivation of any mode may beused.

In some embodiments, the candle may produce an indication of the modeselected. It at least one embodiment, when the user depresses thecontrol switch, the light source may flash any number of times toindicate a certain mode has been selected.

Flicker Mode

The natural flicker may be controlled by one or more methods, including,but not limited to a random signal method. A random signal method maygenerate one or more random signals resulting in a natural “flicker”from the light source. As noted above, FIG. 5A is an electricalschematic for one embodiment of the circuit board 54 (or PCB 454, and/orin combination with PCB 462 and/or 464) of the present disclosure. Clock76 may be in electrical communication with the power source 52. When thepower source 52, 452 is activated by control switch 30, 32, 432, theclock 76 may provide an input signal to at least the random addressgenerator 84. The random address generator 84 may provide a randomsignal to the dynamic random feedback 80. The dynamic random feedback 80may be or may comprise an analog-to-digital converter, in someembodiments. The random signal may vary in one or more aspectsincluding, but not limited to, amplitude, frequency, and duty cycle. Theduty cycle may be the period of time it takes for a signal to completean on-and-off cycle. In at least one embodiment, the random addressgenerator 84 may use pulse-width modulation to modify the signal, whichresults in controlling the power supplied to the light source.Pulse-width modulation may be used to manipulate (increase or decrease)the power a light source receives at very high rates. This manipulationmay result in a perceived flicker as the light source is quickly changedfrom high luminescence to low luminesce and back again.

The dynamic random feedback 80 may convert the random signal to adigital signal which is then transmitted to the control module 90. Thecontrol module may be or may comprise a random sequence generator, insome embodiments. The control module may control one or more lightsource aspects, including but not limited to light brightness and time.The control module 90 may manipulate the random signal received from thedynamic random feedback 80 into a second random signal; although such isnot required. The second random signal may also vary in one or moreaspects to control the brightness and duration in the light source. Inone embodiment, the second random signal variations may include, but arenot limited to, amplitude, frequency, and duty cycle. In at least oneembodiment, the control module 90 may also use pulse-width modulation tomodify the signal. The second random signal from the control module 90may be output via output 92 to the light source 56, 456.

In one embodiment, using LED light diodes, the second random signal maybe output to one or more diodes. As illustrated in FIG. 5B the controlmodule 90 may convert the random signal 92 a into one or more randomsignals 92 b, 92 c, and 92 d each being output to a separate diode viaoutput 92. The signal transmitted randomly to one or more of the diodesof the LED 56, 456 may produce a natural “flicker” of light to the humaneye.

The natural “flicker” may have a 72-hour cycle, in some embodiments. A72-hour cycle may provide an optimal battery life, in some embodiments,where a battery is used as the power source. For example, a random, orseemingly random pattern may be used for a 72-hour cycle, at the end ofwhich the random pattern may then repeat. In some embodiments, a 24-hourcycle may be used. In other embodiments, a 48-hour cycle may be used. Itshould be understood that a cycle of any duration may be used.

Static Mode

A light source in static mode may be on, and may not flicker. In variousembodiments, the static mode may be set to varying degrees ofluminosity. That is, the light source may be dimmed to one or morelevels. The power supply 52, 452, may supply power directly to the lightsource 56, 456, in some embodiments. In other embodiments, the powersupply may pass through the clock 76 before reaching the light source56, 456, thereby allowing a timer mode to be activated.

Timer Mode

The flameless candle may have a timer, where the light remains on for apredetermined timed period. In some embodiments, the timed period may beautomatically set. For example, activation of the timer may keep thelight source on for one hour and then turn the candle off. In otherembodiments, the user may set the timer to any desired time. In oneembodiment, the user may select the timer by depressing a control buttonuntil the timer mode is selected. In one example, the light source mayflash three times to indicate the timer mode has been selected. The usermay then push the control switch any number of desired times, eachdepression of the control switch adding a predetermined period of time.In other embodiments, there may be a USB port that a user may plug intothe candle with preloaded timer settings. In still another, there may bea separate control switch for the timer mode, or two or more controlswitches may, together, activate the timer mode. Any suitable method toset a timer for the candle may be used.

Scented Flameless Candle

A flameless candle of the present disclosure may additionally oralternatively have a scented component that may provide a scent or aromato the surrounding environment. In some embodiments, the scentedcomponent may be a scented cartridge. The scent may be diffused throughthe cartridge and into the surrounding environment when heat or anelectric current is applied to the scent cartridge, in some embodiments.

Referring to FIG. 6, a scent cartridge 40, may be comprised of a topsurface 112, a bottom surface 113, and an outer sidewall 114 thatextends between the bottom surface 113 and the top surface 112. In someembodiments, the scent cartridge 40 may further comprise an innersidewall 115, extending between the bottom surface 113 and the topsurface 112, thereby defining a hole 116. The top surface 112, bottomsurface 113, and sidewalls 114, 115 may cooperate to define a chamber,or cavity 119 (seen in FIG. 7). The cavity 119 may contain one or morefragrance impregnated materials. In one embodiment, the fragranceimpregnated material may be a fragrant liquid. In another embodiment,the fragrance impregnated material may be a fragrant disk. Any suitablefragrant material may be used.

The top surface may comprise one or more openings 117 through which afragrance vapor, or scent, may be diffused. The openings 117 may have adiameter that is between five and ten percent of the outer diameter ofthe scent cartridge 40, in various embodiments. In some embodiments, theopenings 117 have a diameter between about two millimeters and twentymillimeters. In other embodiments, the openings may have any suitablediameter. It should also be understood the openings 117 may be circularholes, slats, or any other suitable opening for diffusing the scent. Theopenings 117 may have a depth that is less than the height of the outersidewall 114, in some embodiments. In other embodiments, the openingsmay have a depth equal to the height of the outer sidewall 114. In stillother embodiments, there may be openings 117 on the surface of innersidewall 115 or outer sidewall 114. The top surface 112 may comprise aplurality of surface features 118. Surface features 118 may include, butare not limited to, bumps, ridges, protrusions, channels, and reliefs.Surface features 118 may further assist with diffusing the scent.

The bottom surface 113 of the scent cartridge 40 may be flat, in someembodiments. In other embodiments, the bottom surface 113 may havesurface features 120 that allow the bottom surface to rest properlywithout shifting within the flameless candle 10, 400. In at least oneembodiment, the bottom surface 113 has a plurality of surface features120 that engage with surface features on the indented central portion 28of the flameless candle 10, 400. By rotating the scent cartridge 40, thesurface features on the bottom surface 113 may substantially alignand/or lock with the surface features on the flameless candle 10, 400 tohold the scented cartridge 110 in place. In some embodiments, the topsurface 112 may have the same configuration of surface features 120 asthe bottom surface 113 allowing the scent cartridge 40 to be flipped orturned over for prolonged use.

The light source, as discussed above, may be disposed inside the body ofthe candle, within the control switch assembly, or in any other suitableposition. In at least one embodiment, the light source may be disposedwithin a central portion of the scent cartridge, allowing the user toreplace the light and the scent simultaneously.

Referring to FIG. 7, a scent cartridge 40 may be disposed within theindented central portion 28, 428 of flameless candle 10, 400. In atleast one embodiment, the bottom surface 113 of the scent cartridge 40may be flush with the base of the indented central portion 28, 428. Inother embodiments, as seen in FIG. 7, the hole 116 may be positionedover a control switch 30, 430, the control switch 30, 430 at leastpartially extending outwardly from the scented cartridge 40. In stillother embodiments, the scented cartridge may be positioned to act on thecontrol switch. For example, the scented cartridge which may, forexample, have no hole 116, may be placed in the indented central portion28, 428. A user may be able to push onto the scented cartridge, whichmay in-turn push onto a push button control switch, thereby depressingthe control switch. In still other embodiments, a control switch 30, 430may be integrated into the scent cartridge.

Activation of a control switch may 30, 430, in addition to activating alight source 56, 456, turn on or off a heating element 160 or otherwiseactivate the scent mode of the candle. To provide heat to the scentcartridge 40, the flameless candle 10, 400 may further comprise aheating element 160, which may be in direct contact with, in nearlydirect contact with, adjacent to, or otherwise close to the scentcartridge 40. However, any suitable position allowing the heatingelement 160 to heat the scent cartridge 40 may be used. The heatingelement 160 may also be in communication with the circuit board 54, 454.In at least one embodiment, the heating element 160 may be situatedbetween the control switch assembly 58, 458 and the scent cartridge 40.In one embodiment, the heating element 160 may have an outer surface 162that cooperates, or mates, with the bottom surface 113 of the scentcartridge 40, in order to apply direct heat. When a user selects toactivate the heating element 160, heat may be applied to the bottomsurface 113 of the scent cartridge 40, resulting in an emission ordiffusion, of the fragrant scent.

FIG. 8 illustrates an example circuit schematic for the circuit board inan embodiment involving a heating element. The circuit 170 may comprisea power source 52, 452, a booster circuit 172, an MCU detection circuit174, a transistor switch 176, and the heating element 160. In someembodiments, the circuit may also include a light source circuit 180.The light source circuit may, in some embodiments, be a circuit such asthat illustrated by FIG. 5A, discussed above. The light source circuitand heating element circuit may share some or all common components. Thepower source 52, 452 may provide a voltage to the MCU detection circuit174 through the booster circuit 172, in some embodiments. In otherembodiments, the power source 52 may provide a voltage directly to theMCU detection circuit. The booster circuit 172 may amplify the voltageobtained from the power source 52, 452 and provide it to the MCUdetection circuit 174. In various embodiments, the booster circuit 172may provide an amplified voltage to the light source circuit 180. TheMCU detection circuit 174 may output high and low electric levels tocontrol the transistor switch 176. The transistor switch 176 may connectthe MCU detection circuit 174 with the heating element 160, therebyaffecting one or more heating element modes as well as the temperatureof the heating element 160. Heating element modes may include, but arenot limited to, on, on-high, on-low, off, or timer.

In various embodiments, based on one or more control switch 30, 32, 432inputs, the MCU detection circuit 174 may output various high and lowelectric levels over a desired time period, herein referred to ashigh-low cycle. The high-low cycle may enable a cyclic on and offinterval of heating by turning the transistor switch 176 on and offbased on the electric levels. For example, a user may select a scentfeature mode having a duration of four hours. The MCU detection circuit174 may output a high-low cycle resulting in the transistor switch 176turning the heating element 160 on for thirty minutes, off for twohours, on for ten minutes, off for thirty minutes, on for ten minutes,off for thirty minutes, and then off. In such an embodiment, when thecontrol switch 30, 32, 430 is pressed again, the cycle may be cancelledand the light source 56, 456 may turn off.

The MCU detection circuit 174 may incorporate a temperature sensor 182,as shown in the detailed circuit schematic example of FIG. 9. Byconverting the temperature change of the heating plate to a voltagechange, the temperature of the heating plate can be tested andcontrolled by the MCU detection circuit 174. When the temperature isequal to or greater than a desired value, the MCU detection circuit 174may turn the transistor switch 176 off, resulting in cutting off powerto the heating element 160. The desired high temperature value may be,at least in part, dependent upon at least the material properties of thescent cartridge 40. In at least one embodiment, the desired hightemperature value may be about fifty degrees C. (one-hundred and twentytwo degrees F.). In general, the desired high temperature value can bebetween about forty-five degrees C. (about one-hundred and thirteendegrees F.) and fifty-five degrees C. (about one-hundred and thirty onedegrees F.). When the temperature is equal to or lower than a desiredvalue, the MCU detection circuit 174 may turn the transistor switch 176on, sending power to the heating element 160, and thereby turning theheating element 160 on. In at least one embodiment, the desired lowtemperature value may be about five degrees C. lower than the desiredhigh temperature value. The desired low temperature value may be, atleast in part, dependent upon the material properties of the scentcartridge 40. In at least one embodiment, the desired low temperaturevalue is about forty-five degrees C. (about one-hundred degrees F.). Ingeneral, the desired low temperature value can be between aboutthirty-eight degrees C. (about one-hundred degrees F.) and fifty degreesC. (about one-hundred and twenty-two degrees F.). However, it should beunderstood that any suitable temperature (s) to heat the heating element160 may be used and are within the scope of the present disclosure.

In at least one embodiment as shown in FIGS. 4B and 4G, the sleeves410A, 410B may incorporate a scent. A user may be able to remove andexchange the sleeve, as discussed above, in order to change the scent. Aheating element, fan, or other method to disperse the scent may belocated on the inner core 400B. The heating element 160, a fan, and/orany other suitable method may be activated using one or more controlswitches 30, 430, as discussed above.

In someembodiments, the sensing component may be a motion sensor that may allowa user to use hand motions, or other motions, to select variousfunctions, or modes, of the flameless candle. The modes may include, butare not limited to, whether the light is on or off, whether the light isin a static mode or flicker mode, the duration the light is on, thecolor of the light, the luminescence of the light, and whether a scentmode is on. In other embodiments, the sensing component may be anoptical sensor that may allow one or more modes to be selected based onthe ambient light in the surrounding environment. For example, when theambient light is reduced, such as at dusk, the optical sensor may detectthe change and turn the flameless candle's light on. In still otherembodiments, the sensing component may be an audio sensor that may allowthe user to use audio cues to select various functions, or modes, of theflameless candle. In one embodiment, the sensing component may be ableto detect air movement, allowing a user to select a various mode, suchas turning the flameless candle off, by blowing on the sensor,simulating a method of blowing out a traditional true flame candle. Insome embodiments, the sensing component may be a Bluetooth, radio, orother wireless component able to receive a wireless signal from acomputer, remote, handheld device, or any other suitable device. Forexample, a user may select a flicker mode on a timer for two hours fromher handheld device. The device may transmit a signal that may bereceived by the sensing component in the wireless candle, resulting inthe candle being configured to remain in flicker mode for two hours andthen turn off. One or more sensors may be used in various embodiments ofthe present disclosure.

A flameless candle may comprise a motion sensor, in various embodiments.As seen in FIGS. 9A-9B a motion sensor 70 may be disposed within theindented central portion 28. In some embodiments, the motion sensor 70may be radially offset from the center of the base 29 of the centralportion 28, 428. In various embodiments where a scent cartridge may beused, the motion sensor 70 may be spaced sufficiently away from thecenter of the base 29 so as not to be covered by the scent cartridge. Insome embodiments, the motion sensor 70 may be integrated with the uppercontrol switch 30, 430. In at least one embodiment the motion sensor 70,upper control switch 30, 430, and light source 56, 456 may becollectively integrated. In other embodiments as seen in FIG. 10, themotion sensor 70 may be embedded within the body 20, 420 of theflameless candle 10, 400. By embedding the motion sensor 70 into thebody 20, 420 of the flameless candle 10, 400, the candle may haveadditional functionality while being aesthetically similar to atraditional candle. Any suitable location to embed the motion sensor 70may be used and is within the scope of the present disclosure.

A motion sensor assembly may house the motion sensor. Similar to thecontrol switch assembly discussed above, the motion sensor assembly maybe in communication with the power source, the light source, and acircuit board. Referring additionally to the exploded view in FIG. 11,when installed within the cavity 49, the motion sensor assembly 61 maybe flush with the surrounding surface of the body 20, 420 and/or may beflush with the indented central portion on the top surface 22, 422. Insome embodiments, the motion sensor assembly 61 is made from a wax,paraffin, glass, polymeric materials, or combinations thereof. In someembodiments, the configuration of the motion sensor assembly and theselected material may have desirable translucent, luminescent andaesthetic properties to mimic the look and feel of a traditional candle.

The motion sensor may emit electromagnetic waves. By using differenthand motions, electromagnetic induction modules may produce differentwaveform outputs to perform different product function statuses (such ason or off). In various embodiments, by activating the motion sensor 70,the light source 56, 456 of the candle may be illuminated. In at leastone embodiment, a control switch may activate the power supply beforethe motion sensor may change the mode.

In one particular embodiment, the light source 56, 456 may be off andthe candle may be in a standby mode. When the power source 52, 452 isturned on, at least one oscillator of the control circuit 55 may outputa high level voltage continuously to a transistor circuit 72 of thecircuit board 354. This high level voltage may be continuously suppliedto a first transistor of the transistor circuit 72 until it reaches asaturation conduction. The voltage may then pass through to a secondtransistor of the transistor circuit 72, whereby the second transistoris conducted. The voltage may then pass to the light source 56, 456, inessence turning the light source on. The voltage may then pass back tothe control circuit 55 as three outputs 72A, 72B, and 72C. The threeoutputs 72A, 72B, and 72C may form square wave outputs, therebyaffecting the amplitude of the voltage provided to the light source,which may cause the light source 56 to flash. In some embodiments, thecontrol circuit 55 may utilize pulse modulation to control brightness ofthe light source 56, 456.
